btw .. you put the equation twice it's supposed to be " -5x+9y=-18 "
Answer:
$1.30
Step-by-step explanation:
Let x = the cost of the pencil
Let x + .80 = the cost of the pen
Let 4(x + .80) = the cost of the binder
x + x + .80 + 4(x + .80) = 11.80
2x + .80 + 4x + 3.20 = 11.80
6x + 4.00 = 11.80
6x = 7.80
x = $1.30
x + .80 = $2.10
4(x + .80) = $8.40
Distribute it out. you should end up with (y^2+7y) + (5y+35) add the 7y and the 5y to get 12y. you will have y^2+12y+35. tbh i have no idea what to do from there. its been so long since i have studied this
